TOBACCO-PIPE.

Application filed April 3, 1916.

To all whom it may concern:

Be it known that I, RICHARD J. REYNOLDS, of Winston-Salem, in the county of Forsyth and State of North Carolina, have invented certain new and useful Improvements in Tobacco-Pipes, of which the following is a specification. D

The object of the present invention 13 to provide a tobacco pipe of such a construction that the nicotin is collected separately from the saliva from the mouth of the smoker and both nicotin and saliva are removed in the act of discharging the ashes from the pipe.

The improved pipe construction to obtain this object is illustrated in the accompanying drawings, wherein Figure 1, is a sectional view of a pipe containing the improvement. F g.2, 1s a perspective view of a cup which is inserted within the bowl of a pipe. Flgs. 3 and 4, are sections of modifications.

Referring first to Figs. 1 and 2, the p pe comprises a bowl A, and a stem B, which may be of an construction and relation to each other an may be of any materials used in pipe making. The bottom of the bowl 1s in communication with the mouthplece by means of a passage a, in the stem which leads to the end of the mouthpiece.

Within the bowl is a cup 0. Th1s cup is composed of a single piece of sheet metal bent into the illustrated shape. This cup can be made of silver, aluminum, nlckel, or other sheet metal.

The cup C, has at its lower end a dlaphragm b, which divides the bowl mto two chambers. The chamber above the diaphragm b, is open mouthed and receives the tobacco. The chamber D, below the d aphragm is in immediate communication with the stem passage a. This diaphragm b, is conical, or funnel-form, extending upwardly from its periphery to the middle of the bowl. It has an air passage 0, at its middle and highest part only. The annular side wall 0?, of the cup is of a shape to fit the lower portion of the bowl A. It is resilient and sufficiently wide at the mouth so as to be sprung slightly when forced mto place 1n the bowl so as to be adequately held 1n place by friction. The diaphragm is a proper distance from the mouth of the bowl so as to furn sh a sufliciently large chamber E, to receive Specification of Letters Patent.

a usual charge of tobacco. The cup fits the bowl sufliciently close so that the only passage for air to the stem passage a, is through the single central passage 0.

Any nicotin is collected in the channel 6, above the diaphragm and below the air passage c, so that it does not pass into the lower air chamber D of the bowl and hence cannot be drawn into the mouth of the smoker. Any saliva from the mouth of the smoker which passes into the chamber D, through the stem passage or, collects therein and does not come in contact with the tobacco while being smoked.

After a charge of tobacco has been smoked the bowl will be turned upside down for the purpose of knocking out the ashes. When the bowl is thus inverted any nicotin which is thus collected in the channel 6, will flow outwardly into the ashes and will be discharged with them. Likewise, any saliva which is collected in the chamber D, will run into the funnel constituted by the tapering diaphragm b, and out through the air passage 0, into the ash. Accordingly, the nicotin and the saliva will mingle with the ash and will be discharged therewith when the bowl is cleaned.

The pipe provided with the cup C, has the following advantages:

The funnel-form diaphragm of the cup facing upwardly catches the nicotin which accumulates in smoking.

The cu prevents nicotin from intermingling wit the saliva from the mouth and thus prevents this disagreeable mixture from getting into the stem of the pipe and then into the mouth of the smoker.

The space or chamber D, under the cup forms a cooling air chamber and acts as a' creased since they are largely due to'fine particles of tobacco being drawn'into the stem and mixing with the nicotinand saliva. By eliminating this strong odor, sweetness is added to the pipe.

, Fig. 4, illustrates a modified construction of the cup. The cup at its rim is provided with a down and out-turningyielding flange 7", which by its elasticity aids in maintaining the cup in place in the bowl; This yielding down and out-turned flange is compressed when inserted in the pipe and hence acts elastically to hold the Cup in place. This figure also illustrates a hooked-end tool F,

which can be inserted 1n the air hole 0, and

G'opies of this patent may beobtained for naaaeas bowl, ar'detachable open-mouthed resilient cupshallow relatively to the-depth of the bowl and sprung gintothe -bowl and-elastically fitting therein atthe lower part thereof only, said cup having imperforate side walls and at its lower end a funnel-form diaphragm extending upwardly from the periphery of the cup toward the middle thereof, said diaphragm having an air channel at its apex only, being'otherwise imperforate, this funnel-form diaphragm dividing the pipe bowl into two chambers; an upper chamber to receive the c'hargeoftobacco, this chamber having a nicotiircollecting annular air channelat its periphery below the air opening at the apex of thediaphragm, and" a lower air chamber below the funnel-form diaphragm constituting both cooling" chamber and a chamber for collectingthe saliva which may flow from"them'outh*of= the smoker into it through the communicat in'g passage in the stem;

In witness whereof; I have hereunto signed my name."
